## Summary description

Spiral hexagonal 25 mm wood drill bit from GRAPHITE (model 57H259). Designed for drilling into wood, the bit features a spiral flute for efficient chip removal and a hex shank for secure chuck or quick-change adapter use. Suitable for hand drills and power drills in woodworking, joinery and general DIY applications.

## Long description

GRAPHITE spiral hex wood drill bit 25 mm (57H259) is designed for reliable and efficient drilling in soft and hard wood. The spiral flute geometry promotes fast chip evacuation, reducing clogging and allowing a cleaner hole. The hex shank fits standard chucks and quick-change adapters, ensuring a firm grip and simple bit changes for hand drills and corded or cordless power drills used in woodworking and DIY tasks.
Advantages
The spiral flute removes chips quickly, improving drilling speed and hole quality while reducing heat build-up. The hexagonal shank provides secure fastening in chucks and quick-change holders to minimize slipping during high-torque applications. The bit’s 25 mm diameter allows drilling large-diameter holes in a single pass, suitable for creating clearings for fittings, dowels or cable passages. The solid construction and precise geometry contribute to consistent performance and longer service life when used appropriately.
Suitable for
Drilling clearance and through-holes in soft and hard wood
Creating openings for dowels, plugs, and cable routing
Carpentry, joinery and general woodworking tasks
Home improvement and DIY projects using hand or power drills
Key specifications
Diameter: 25 mm
Flute type: Spiral flute for efficient chip evacuation
Shank type: Hexagonal shank for secure chuck and quick-change compatibility
Intended material: Wood (softwood and hardwood)
Compatible tools: Hand drills, corded and cordless power drills
How to use
Secure the drill bit in the drill chuck or quick-change adapter until it is firmly held. Mark the drilling position on the workpiece and, if necessary, clamp the workpiece to prevent movement. Start drilling at low speed to establish the hole, then increase speed as needed while maintaining firm, steady pressure. Withdraw the bit periodically for deep holes to clear chips and prevent clogging. After use, clean wood debris from the flute and store the bit in a dry place.
Usage recommendations
Use appropriate drill speeds for the wood type: lower speeds for hard wood and higher speeds for soft wood. Apply steady axial pressure without forcing the bit, and keep the workpiece secured. For longer service life, avoid excessive heat by clearing chips regularly and allowing the bit to cool between long drilling runs.
